  1. 1. Geospatial Knowledge Discovery using Volunteered Geographic Information : a Complex System Perspective

    Författare :Tao Jia; Bin Jiang; Yifang Ban; Itzhak Benenson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; knowledge discovery; urban systems; complex system; VGI; OSM; GPS tracking dataset; scaling; heavy-tailed distribution detection; urban sprawl; Zipf’s law; human activity mobility patterns; agent-based modeling; complex network.;

    Sammanfattning : The continuous progression of urbanization has resulted in an increasing number of people living in cities or towns. In parallel, advancements in technologies, such as the Internet, telecommunications, and transportation, have allowed for better connectivity among people. LÄS MER

  2. 2. Structures in complex systems : Playing dice with networks and books

    Författare :Sebastian Bernhardsson; Petter Minnhagen; Stefan Bornholdt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; networks; statistical physics; biological networks; quantitative linguistics; word frequencies.; Physics; Fysik;

    Sammanfattning : Complex systems are neither perfectly regular nor completely random. They consist of a multitude of players who, in many cases, playtogether in a way that makes their combined strength greater than the sum of their individual achievements. LÄS MER

  3. 3. Organization of information pathways in complex networks

    Författare :Atieh Mirshahvalad; Martin Rosvall; Santo Fortunato; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; Complex Networks; Information; Communication; Community Detection; Significance Analysis; Resampling; Information Spreading.; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : A shuman beings, we are continuously struggling to comprehend the mechanism of dierent natural systems. Many times, we face a complex system where the emergent properties of the system at a global level can not be explained by a simple aggregation of the system's components at the micro-level. LÄS MER

  4. 4. Modeling Driver Behavior : A Control Theory Based Approach

    Författare :Katja Vogel; Lars Åberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the project, which led to this thesis, was to suggest a micro-level driver behavior model, which would allow estimating the effects of safety measures on road traffic safety. The empirical research on driver behavior should be conducted in urban areas, because they are much less explored than rural areas, even though most non-fatal accidents occur in urban areas. LÄS MER

  5. 5. Complex Phase Behavior in Thermoelectric Mg2Si1-xSnx Alloys and Development of Transient Plane Source Method for Structural Characterization

    Författare :Andrey Sizov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiphase structure; quality control; inhomogeneity tests; Rietveld refinement; Transient Plane Source method; isotropic and anisotropic materials; defects detection; advance measurements of thermal properties; X-ray diffraction; structural characterization; spark plasma sintering; magnesium silicide-stannide alloys; complex behavior; thermoelectric properties; thermal conductivity vs. probing depth;

    Sammanfattning : The thermoelectric effect was discovered nearly 200 years ago, but it started to be utilized for waste heat recovery only fairly recently. From an economical point of view, such applications requires a cheap and efficient material, which is able to convert heat energy into electricity. LÄS MER
